Content Management with Joomla

I've just built a website for Write-Minded.co.uk, using Joomla! Content Management software and I'm very pleased at how easy and user friendly it is, both for me to develop and for the owners of the site, who can log on and add or update articles from the site's homepage.
In the past I've turned down work because I only offered hand built websites, but now I'll be able to provide function rich websites to  potential clients.
Content Management will allow clients to update their websites, giving them greater control over content as well as freeing up my time for building new websites rather than updating old ones. A win-win situation!
